Wash the line and run out all the twists properly and then fit it to the boat. DO NOT "bundle" it together like any sailors would between these operations and fitting it to the boat. This reintroduces the twists again.

The only exception is to "bundle" it up with figure 8 loops and not normal loops. Then the line can be fitted to the mast straight from the bundle without introducing any twists.

Another good modification is to replace the turning block on the trampoline by a steel ring. The steel rings allows the kinks to pass while a microblock doesn't. The kinks are only created in the slack portion of the halyard line and never in the tensioned portion. Bungee-ing the slack portion on the tramp will therefor work to reduce kinks and /or pull then out when they do form.

Alot can be done to have the setup be largely kink free and/or kink acceptant.

6 mm line is too thick for the spi halyard. It will be heavy and needlessly thick. 4 mm is enough of the line allows your hands to have some grib. The dyneema core is very slippery and I refuse to "hand" it as a crew. Best is too just use the unmodified line as a halyard and only strip some of the mantle off of the last few feet.
